 var highlight_dates = {};
    highlight_dates[ new Date( '03/10/2020' )] = new Date( '03/10/2020' );
    highlight_dates[ new Date( '02/21/2020' )] = new Date( '02/21/2020' );
    
    $('#datepicker').datepicker({
       beforeShowDay: function(date) {
          var highlight = highlight_dates[date];
            if( highlight ) {
                 return [true, "class-to-highlight", 'Special Event'];
            } else {
                 return [true, '', ''];
            }
       }
    });

 .class-to-highlight{
           background-color: #ff0;
       }

you can use bdeforeShowDay function with highlighter css.

var highlightDays = ["2020-2-21","2020-2-23","2020-2-11","2020-3-21",];
var date = new Date();
jQuery(document).ready(function() { 
    $( "#datepicker").datepicker({ 
        dateFormat: 'yy-mm-dd',
        beforeShowDay: function(date) {
            var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
            for (i = 0; i < highlightDays.length; i++) {
                if($.inArray(y + '-' + (m+1) + '-' + d,highlightDays) != -1) {
                    return [true, 'highlight', ''];
                }
            }
            return [true];
        }
    });
});

.highlight{
       background-color: red;
   }
